[0041] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0042] It should be noted that all directional indications in the embodiments of the present application (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0043] In this application, unless otherwise specified or limited, the terms "connection" and "fixation" should be understood in a broad sense. For example, "fixation" can mean fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; internal communication between two elements or interaction between two elements, unless otherwise specified. For those skilled in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0044] In addition, the descriptions of "first", "second", etc. in this application are for descriptive purposes only and should not be understood as indicating or implying their relative importance or implicitly indicating the number of the technical features indicated. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of such features. In addition, the technical solutions between the various embodiments can be combined with each other, but this must be based on the fact that they can be implemented by ordinary technicians in this field. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0045] The first aspect of the present application discloses a delivery device, Figures 1 to 3 As shown, in some embodiments, the dispensing device includes a first actuator 1000, a third actuator 3000, and a driving mechanism 4000. The first actuator 1000 is used to control the dispensing of the first detergent, and the third actuator 3000 is used to control the dispensing of the third detergent. That is, the dispensing device is provided with two locations for storing the first detergent and the third detergent, respectively, a first cavity 6100 for storing the first detergent and a third cavity 6300 for storing the third detergent. When the first actuator 1000 controls the dispensing of the first detergent, the first detergent can be separated from the storage location (first cavity 6100) and directly or indirectly dispensed into the washing chamber under the action of the first actuator 1000. When the third actuator 3000 controls the dispensing of the third detergent, the third detergent can be separated from the storage location (third cavity 6300) and directly or indirectly dispensed into the washing chamber under the action of the third actuator 3000.

[0046] The first detergent is one type of detergent and can be designed primarily for cleaning. The third detergent is one type of detergent and can be designed to assist with cleaning, such as accelerating drying, enhancing gloss, providing antibacterial properties, and removing odors. It is understood that the first and third detergents are not limited to the aforementioned examples and can also be other types. For example, when the dispensing device is applied to a washing machine, the first detergent can be a liquid detergent, such as dishwashing liquid, and the third detergent can be a liquid detergent, such as a rinse aid or deodorizer.

[0047] The movement of the first actuator 1000 and the third actuator 3000 is achieved through the drive mechanism 4000. The drive mechanism 4000 is a component capable of outputting power. The drive mechanism 4000 is configured to drive the movement of the first actuator 1000 and the third actuator 3000. It can be understood that the drive mechanism 4000 is adapted to drive the movement of the first actuator 1000 and the third actuator 3000. This means that the drive mechanism 4000 can drive the movement of the first actuator 1000 when the first detergent is to be dispensed, and can drive the movement of the third actuator 3000 when the third detergent is to be dispensed. When the drive mechanism 4000 activates the first actuator 1000, the first actuator 1000 is activated, thereby controlling the dispensing of the first detergent. When the drive mechanism 4000 activates the third actuator 3000, the third actuator 3000 is activated, thereby controlling the dispensing of the third detergent. It can be understood that, driven by the driving mechanism 4000, the activities of the first actuator 1000 and the third actuator 3000 can be in various forms, including but not limited to rotation, swinging, translation, curved motion, linear reciprocating or compound motion (such as rotation first and then translation), and the same is true for the activities of other components.

[0048] Taking the dispensing device as an example, which includes but is not limited to a dishwasher, the following description will be made in detail. The driving mechanism 4000 drives the first actuator 1000 and the third actuator 3000 to move. The driving mechanism 4000 drives the first actuator 1000 to move, causing the first actuator 1000 to control the dispensing of the first detergent, thereby cleaning the dishes. The driving mechanism 4000 drives the third actuator 3000 to move, causing the third actuator 3000 to control the dispensing of the third detergent, thereby improving the drying effect and increasing the gloss of the dishes.

[0049] It can be seen that, in this embodiment, the driving mechanism 4000 is provided, and the driving mechanism 4000 is configured to drive the first actuator 1000 and the third actuator 3000 to move. In this way, the dispensing of various types of detergents can be controlled by the same set of driving mechanism 4000. Compared with the dispensing devices in the related art, the number of dispensing devices is greatly reduced, which is conducive to reducing the cost of the dispensing devices and reducing the size of the dispensing devices.

[0050] Combine Figures 5 to 7As shown, in some embodiments, the driving mechanism 4000 includes a power source 4001 and a connecting assembly 4002. The power source 4001 and the connecting assembly 4002 cooperate to achieve output. The connecting assembly 4002 plays a transmission role between the power source 4001 and the actuator (the first actuator 1000 and the third actuator 3000). The power source 4001 is suitable for moving in a first direction and a second direction. The first direction and the second direction are opposite, that is, the power source 4001 can move in both the first direction and the second direction. When the power source 4001 moves in the first direction, the power source 4001 is suitable for driving the connecting assembly 4002 to move. The movement of the connecting assembly 4002 thereby drives the movement of the first actuator 1000, and the movement of the first actuator 1000 can control the dispensing of the first detergent. When the power source 4001 moves along the second direction, the power source 4001 is suitable for driving the connecting component 4002 to move. The movement of the connecting component 4002 thereby drives the third actuator 3000 to move. The movement of the third actuator 3000 can control the feeding of the third detergent.

[0051] In this embodiment, the movement of the power source 4001 along the first direction and along the second direction can drive the connecting assembly 4002 to produce different movements. That is, the movement of the connecting assembly 4002 when the power source 4001 moves along the first direction is different from the movement when the power source 4001 moves along the second direction. This can drive the corresponding first actuator 1000 and third actuator 3000. The same power source 4001 can achieve selective delivery of the delivery device, which helps reduce the structural complexity of the drive mechanism 4000. It is understandable that the movement of the power source 4001 along the first direction and along the second direction can be rotation, translation, etc.

[0052] For example, the attached figure shows a power source 4001, and the dispensing device stores the first detergent and the third detergent. When the first detergent and the third detergent need to be dispensed, the power source 4001 moves along the first direction, thereby driving the connecting component 4002 to move, so that the connecting component 4002 drives the first actuator 1000 to move, and the first actuator 1000 moves to achieve the dispensing of the first detergent; the power source 4001 moves along the second direction, thereby driving the connecting component 4002 to move, so that the connecting component 4002 drives the third actuator 3000 to move, and the third actuator 3000 moves to achieve the dispensing of the third detergent.

[0053] In order to adapt to the different actions of the power source 4001 when it moves in the first direction and the second direction, continue to combine Figures 5 to 7As shown, in some embodiments, the connecting component 4002 includes an input component 4101, an intermediate component 4201, a first output component 4301 and a second output component 4401. The power source 4001 is connected to the input component 4101, and the power source 4001 can drive the input component 4101 to move. Since the power source 4001 can move along the first direction and the second direction, the action generated by the input component 4101 when the power source 4001 moves along the first direction is different from the action generated when the power source 4001 moves along the second direction. The input component 4101 is connected to the intermediate component 4201, and the input component 4101 can drive the intermediate component 4201 to move. The different actions generated by the input component 4101 when the power source 4001 moves in the opposite direction also cause the intermediate component 4201 to produce different actions, thereby correspondingly driving the first output component 4301 and the second output component 4401.

[0054] Specifically, when the power source 4001 moves in a first direction, the power source 4001 drives the input member 4101 to move, which in turn drives the intermediate member 4201 to move. Simultaneously, the input member 4101 drives the intermediate member 4201 to move to a first position, causing the intermediate member 4201 to cooperate with the first output member 4301 and drive the first output member 4301 to move. The movement of the first output member 4301 thereby drives the first actuator 1000 to move, thereby dispensing the first detergent. When the power source 4001 moves in a second direction, the power source 4001 drives the input member 4101 to move, which in turn drives the intermediate member 4201 to move. Simultaneously, the input member 4101 drives the intermediate member 4201 to move to a second position, causing the intermediate member 4201 to cooperate with the second output member 4401 and drive the second output member 4401 to move. The movement of the second output member 4401 thereby drives the third actuator 3000 to move, thereby dispensing the third detergent. It can be understood that the middle piece 4201 can move back and forth between a first position and a second position, the first position is the extreme position of the middle piece 4201 when the power source 4001 moves along the first direction, and the second position is the extreme position of the middle piece 4201 when the power source 4001 moves along the second direction, that is, the first position and the second position are the extreme positions of the reciprocating movement of the middle piece 4201.

[0055] Furthermore, in some embodiments, the connecting assembly 4002 includes an input gear 4100, an intermediate gear 4200, a first output gear 4300 and a second output gear 4400. The input gear 4100, the intermediate gear 4200, the first output gear 4300 and the second output gear 4400 are all configured to be rotatable. It can be understood that the input gear 4100 constitutes the input member 4101 mentioned above, the intermediate gear 4200 constitutes the intermediate member 4201 mentioned above, the first output gear 4300 constitutes the first output member 4301 mentioned above, and the second output gear 4400 constitutes the second output member 4401 mentioned above.

[0056] The power source 4001 is connected to the input gear 4100, and the power source 4001 can drive the input gear 4100 to rotate. Since the power source 4001 can move in a first direction and a second direction, the rotation direction of the input gear 4100 when the power source 4001 moves in the first direction is opposite to the rotation direction when the power source 4001 moves in the second direction, that is, the input gear 4100 produces different movements. The input gear 4100 is engaged with the intermediate gear 4200, and the input gear 4100 can drive the intermediate gear 4200 to rotate. Since the input gear 4100 has two opposite rotation directions, the intermediate gear 4200 also has two opposite rotation directions. In this way, the different movements of the input gear 4100 when the power source 4001 moves in opposite directions also cause the intermediate gear 4200 to produce different movements, thereby correspondingly driving the first output member 4301 and the second output member 4401.

[0057] Specifically, when the power source 4001 moves in a first direction, the power source 4001 drives the input gear 4100 to rotate, which in turn drives the intermediate gear 4200 to rotate. Simultaneously, the input gear 4100 drives the intermediate gear 4200 to move to a first position, causing the intermediate gear 4200 to mesh with the first output gear 4300 and drive the first output gear 4300 to rotate. The rotation of the first output gear 4300 thereby drives the first actuator 1000 to move, thereby dispensing the first detergent. When the power source 4001 moves in a second direction, the power source 4001 drives the input gear 4100 to rotate, which in turn drives the intermediate gear 4200 to rotate. Simultaneously, the input gear 4100 drives the intermediate gear 4200 to move to a second position, causing the intermediate gear 4200 to mesh with the second output gear 4400 and drive the second output gear 4400 to rotate. The rotation of the second output gear 4400 thereby drives the third actuator 3000 to move, thereby dispensing the third detergent.

[0058] There are various types of power source 4001. For example, power source 4001 can be a motor, which converts electrical energy into mechanical energy. Specifically, the motor can be a stepper motor, a servo motor, or the like. When power source 4001 is a motor, the motor's ability to move in both the first and second directions is achieved through rotation. Specifically, the motor's shaft can rotate in both the first and second directions. By configuring power source 4001 as a motor, controlling the movement of connection assembly 4002 is facilitated.

[0059] Combine Figures 5 to 8 As shown, in some embodiments, the first actuator 1000 includes a pump body 1100, and the driving mechanism 4000 is suitable for driving the pump body 1100 to move, thereby causing the pump body 1100 to suck and discharge the first detergent. It is understood that the pump body 1100, also known as a pump, is a machine that can suck and discharge fluids. The types of pump bodies 1100 include but are not limited to peristaltic pumps, piston pumps, etc. In this embodiment, the first detergent is a liquid detergent. When the first detergent needs to be added, the driving mechanism 4000 drives the first actuator 1000 to move. The movement of the first actuator 1000 is specifically manifested as the driving mechanism 4000 driving the corresponding structure of the pump body 1100 to move (such as driving the rotating shaft of the pump body 1100 to rotate), so that the pump body 1100 sucks the first detergent from the first cavity 6100 and discharges the first detergent, thereby achieving the addition of the first detergent.

[0060] It is understandable that current dispensing devices have different dispensing methods to adapt to different similar washing appliances. As washing appliances are upgraded, the dispensing methods of dispensing devices also need to be improved to meet more needs. Therefore, the above-mentioned drive mechanism 4000 driving the pump body 1100 can be applied not only to the dispensing device of this application, but also to other types of dispensing devices. For example, in other embodiments, the dispensing device includes a drive mechanism 4000 and a first actuator 1000. The first actuator 1000 includes a pump body 1100. The drive mechanism 4000 is suitable for driving the rotating shaft of the pump body 1100 to rotate, so that the pump body 1100 sucks and discharges the first detergent.

[0061] Further, combined with Figure 8 As shown, in some embodiments, the driving mechanism 4000 includes a first output gear 4300, which is coaxially arranged with the rotating shaft of the pump body 1100. The driving mechanism 4000 is suitable for driving the rotating shaft of the pump body 1100 to rotate through the first output gear 4300, so that the pump body 1100 absorbs and discharges the first detergent.

[0062] Specifically, by coaxially aligning the first output gear 4300 with the rotating shaft of the pump body 1100 , the first output gear 4300 can drive the rotating shaft of the pump body 1100 to rotate coaxially, which is beneficial for saving space. Taking the driving mechanism 4000 including a power source 4001 and a connecting component 4002, and the connecting component 4002 including an input gear 4100, an intermediate gear 4200, a first output gear 4300 and a second output gear 4400 as an example, when the power source 4001 moves along the first direction, the power source 4001 drives the input gear 4100 to rotate, and the rotation of the input gear 4100 drives the intermediate gear 4200 to rotate. At the same time, the input gear 4100 drives the intermediate gear 4200 to move to the first position, so that the intermediate gear 4200 is engaged with the first output gear 4300 and drives the first output gear 4300 to rotate. The rotation of the first output gear 4300 drives the rotating shaft of the pump body 1100 to rotate, and the pump body 1100 sucks in the first detergent and discharges the first detergent, thereby realizing the delivery of the first detergent.

[0063] Combine Figures 5 to 7 as well as Figures 9 and 10 As shown, in some embodiments, the driving mechanism 4000 is adapted to drive the third actuator 3000 to move so as to disengage the third actuator 3000 from the communication port 6310 of the dispensing device and allow the third detergent to flow out of the communication port 6310. It is understood that the dispensing device is provided with a location (third cavity 6300) for storing the third detergent, which is provided with the communication port 6310. The third actuator 3000 is adapted to disengage from and block the communication port 6310. When the third detergent is placed in this location, the third actuator 3000 needs to block the communication port 6310, preventing the third detergent from leaving the third cavity 6300 and flowing out of the communication port 6310. When the third actuator 3000 is disengaged from the communication port 6310, the third detergent can flow out of the communication port 6310, thereby achieving the dispensing of the third detergent. In this embodiment, the third detergent is a liquid detergent such as a rinse aid. When the third detergent needs to be added, the driving mechanism 4000 drives the third actuator 3000 to move, so that the third actuator 3000 is separated from the connecting port 6310, and the third detergent flows out from the connecting port 6310, and then is added directly or indirectly.

[0064] It is understandable that current dispensing devices have different dispensing methods to adapt to different similar washing appliances. As washing appliances are upgraded, the dispensing methods of dispensing devices also need to be improved to meet more needs. Therefore, the above-mentioned third actuator 3000 and drive mechanism 4000 can be used not only in the dispensing device of this application, but also in other types of dispensing devices. For example, in other embodiments, the dispensing device includes a drive mechanism 4000 and a third actuator 3000, and the drive mechanism 4000 is suitable for driving the third actuator 3000 to move so that the third actuator 3000 is separated from the connecting port 6310 of the dispensing device and the third detergent flows out of the connecting port 6310.

[0065] Combine Figure 9 and Figure 10 As shown, in some embodiments, the third actuator 3000 is provided with a rack portion 3121, and the driving mechanism 4000 is adapted to engage with the rack portion 3121 to drive the movement of the third actuator 3000. The movement of the third actuator 3000 is specifically manifested by the driving mechanism 4000 driving the rack portion 3121, thereby causing the third actuator 3000 to move, thereby disengaging from the communication port 6310. The provision of the rack enables linear displacement of the third actuator 3000, more effectively disengaging from the communication port 6310.

[0066] Combine Figure 9 and Figure 10 As shown, in some embodiments, the drive mechanism 4000 includes a second output gear 4400. The drive mechanism 4000 is adapted to drive the rack portion 3121 to move via the second output gear 4400. The second output gear 4400 is provided with a shifting tooth portion 4420. When the second output gear 4400 rotates, the shifting tooth portion 4420 is engaged with the rack portion 3121 to drive the third actuator 3000 to move. When the second output gear 4400 rotates, the shifting tooth portion 4420 rotates with it. Since the shifting tooth portion 4420 is engaged with the rack portion 3121, the rotation of the second output gear 4400 drives the rack portion 3121 to move. The movement of the rack portion 3121 can cause the third actuator 3000 to disengage from the communication port 6310.

[0067] Taking the driving mechanism 4000 including the power source 4001 and the connecting component 4002, and the connecting component 4002 including the input gear 4100, the intermediate gear 4200, the first output gear 4300 and the second output gear 4400 as an example, when the power source 4001 moves along the second direction, the power source 4001 drives the input gear 4100 to rotate, and the rotation of the input gear 4100 drives the intermediate gear 4200 to rotate. At the same time, the input gear 4100 drives the intermediate gear 4200 to move to the second position, so that the intermediate gear 4200 is engaged with the second output gear 4400 and drives the second output gear 4400 to rotate. The rotation of the second output gear 4400 drives the rack part 3121 to move through the gear shifting part 4420. The movement of the rack part 3121 causes the third actuator 3000 to disengage from the connecting port 6310, thereby realizing the delivery of the third detergent.

[0068] Combine Figure 9 and Figure 10 As shown, in some embodiments, the second output gear 4400 is provided with a gear portion 4410, and the driving mechanism 4000 further includes an input gear 4100. The input gear 4100 is adapted to drive the second output gear 4400 to rotate via the gear portion 4410. The gear portion 4410 and the shifting gear portion 4420 are arranged along the axial direction of the second output gear 4400. In this embodiment, the gear portion 4410 of the second output gear 4400 is configured to be in transmission connection (directly or indirectly) with the input gear 4100. If the gear portion 4410 of the second output gear 4400 also meshes with the rack portion 3121, this would not be conducive to reducing space usage. However, arranging the gear portion 4410 and the shifting gear portion 4420 along the axial direction of the second output gear 4400 can help reduce space usage.

[0069] Optionally, combined Figure 9 As shown, along the radial direction of the second output gear 4400, the maximum distance between the center of the second output gear 4400 and the gear portion 4410 is greater than the maximum distance between the center of the second output gear 4400 and the shifting gear portion 4420. With this arrangement, along the axial direction of the second output gear 4400, the rack portion 3121 and even the entire third actuator 3000 at least partially overlap with the second output gear 4400, thereby reducing space usage.

[0070] Combine Figure 9 As shown, in some embodiments, the tooth portion 4420 is suitable for separating from the rack portion 3121 after the third actuator 3000 is separated from the connecting port 6310, and the delivery device also includes a third elastic member 5300, which is suitable for generating force on the third actuator 3000 to drive the third actuator 3000 to move toward the connecting port 6310 to block the connecting port 6310 after the tooth portion 4420 and the rack portion 3121 are separated.

[0071] Specifically, the tooth shifting portion 4420 is not arranged along the entire circumference of the second output gear 4400, but is arranged at a certain position on the circumference of the second output gear 4400. In this way, when the second output gear 4400 rotates, the tooth shifting portion 4420 engages with the rack portion 3121 and drives the third actuator 3000 to disengage from the connecting port 6310. When the second output gear 4400 continues to rotate a certain angle, the tooth shifting portion 4420 separates from the rack portion 3121. In this embodiment, by providing a third elastic member 5300, the third elastic member 5300 generates a force on the third actuator 3000, that is, when the second output gear 4400 rotates and the tooth shift portion 4420 engages with the rack portion 3121, thereby driving the third actuator 3000 to disengage from the connecting port 6310, the third elastic member 5300 undergoes elastic deformation and accumulates elastic potential energy and generates a force on the third actuator 3000. When the tooth shift portion 4420 is separated from the rack portion 3121, the third elastic member 5300 releases the elastic potential energy, thereby driving the third actuator 3000 to move toward the connecting port 6310 and block the connecting port 6310. In this way, when the driving mechanism 4000 drives the third actuator 3000, the connecting port 6310 can be blocked without changing the direction of movement, which is more conducive to the control of the driving mechanism 4000.

[0072] Optionally, in some embodiments, the tooth shifting portion 4420 is adapted to alternately engage and disengage with the rack portion 3121 when the second output gear 4400 rotates, thereby enabling multiple dosing of the third detergent. For example, when the second output gear 4400 rotates, the tooth shifting portion 4420 sequentially engages, disengages, engages, and disengages with the rack portion 3121 in four steps: the first step disengages the third actuator 3000 from the communication port 6310; the second step blocks the communication port 6310; the third step disengages the third actuator 3000 from the communication port 6310; and the fourth step blocks the communication port 6310, thereby enabling two dosings of the third detergent.

[0073] Combine Figure 10 As shown, in some embodiments, the third actuator 3000 includes a flexible sealing plug 3200. The third actuator 3000 is adapted to be separated from the communication port 6310 and to seal the communication port 6310 through the sealing plug 3200. Specifically, the flexible sealing plug 3200 is elastically deformable. For example, the sealing plug 3200 is made of a material such as silicone or rubber. With this configuration, when the third actuator 3000 seals the communication port 6310, the sealing plug 3200 contacts and seals the communication port 6310, causing the sealing plug 3200 to deform, thereby better sealing the communication port 6310.

[0074] Optionally, the third actuator 3000 includes a frame member 3100 and a sealing plug 3200, which are sealingly connected to the frame member 3100. The frame member 3100 is provided with a rack portion 3121. It is understood that the frame member 3100 serves as a supporting framework for the sealing plug 3200 and is designed to have high structural strength. Through the provision of the frame member 3100, the frame member 3100 can drive the sealing plug 3200 to separate from the communication port 6310 and block the communication port 6310. When blocking the communication port 6310, the frame member 3100 can squeeze the sealing plug 3200 to achieve a better sealing effect.

[0075] Further, combined with Figure 10 As shown, in some embodiments, the framework member 3100 includes a support rod 3110 and a transmission rod 3120. The support rod 3110 and the transmission rod 3120 are separate components and are interconnected. The sealing plug 3200 is provided on the support rod 3110, and the transmission rod 3120 is provided with a rack portion 3121. The support rod 3110 and the transmission rod 3120 are separate components, that is, the support rod 3110 and the transmission rod 3120 constitute independent components and are then connected together by a connection method. The provision of separate support rods 3110 and transmission rods 3120 facilitates the manufacture of the framework member 3100, reduces the manufacturing difficulty, and facilitates the structural arrangement. The support rod 3110 and the transmission rod 3120 can be connected in a variety of ways, such as screws, plug-in connections, snap-on connections, and other methods. In this embodiment, the support rod 3110 and the transmission rod 3120 are plug-in connections, which is convenient and quick.

[0076] The second aspect of the present application discloses a washing appliance, including but not limited to a dishwasher, a washing machine, etc., which includes the dispensing device of the above-mentioned embodiment. In this embodiment, a driving mechanism 4000 is provided, and the driving mechanism 4000 is configured to drive the first actuator 1000 and the third actuator 3000 to move. In this way, the dispensing of multiple types of detergents can be controlled under the action of the same set of driving mechanisms 4000. Compared with the dispensing devices in the related art, the number of dispensing devices is greatly reduced, which is conducive to reducing the cost of the dispensing devices and reducing the size of the dispensing devices. It can be understood that the dispensing device of the washing appliance of this embodiment adopts the technical solution of the above-mentioned embodiment, and therefore has at least the beneficial effects brought about by the technical solution of the above-mentioned embodiment, which will not be repeated here.
